internal compiler errors (derived type bindings)

Dear all,

I am posting two situations that rise internal compiler errors in the hope that it helps others to avoid lengthy and annoining searches for the cause of the compiler crash, and in case Intel engineers are interested.
Both errors are triggered by invalid uses of type-bound procedures, such as forgetting the parentheses in a function call.

source A:

module m
    ! derived type ----------
    type :: X
        integer :: x_comp
    contains 
        procedure, nopass :: x_bind
    end type
contains
    subroutine x_bind()
    end subroutine

    ! trigger crash ---------
    subroutine CRASH()
        type(X) :: myX

        ! use binding name as keyword
        myX = X(x_bind=1.0d0)
    end subroutine
end module

! compiler output -----------
! test9.f90: catastrophic error: **Internal compiler error: segmentation violation signal raised** Please report this error along with the circumstances in which it occurred in a Software Problem Report.  Note: File and line given may not be explicit cause of this error.
! compilation aborted for test9.f90 (code 1)

Source B:

module m
    ! derived type ----------
    type :: X
    contains 
        procedure, nopass :: x_bind
    end type
contains
    subroutine x_bind
    end subroutine

    ! trigger crash ---------
    subroutine crash()
        type(X) :: myX
        logical :: expr

        ! apply any logical operator to non-existing
        ! component that corresponds to a binding name
        expr = .not. myX%x_bind
    end subroutine
end module

! compiler output -----------
! test10.f90(18): catastrophic error: **Internal compiler error: internal abort** Please report this error along with the circumstances in which it occurred in a Software Problem Report.  Note: File and line given may not be explicit cause of this error.
! compilation aborted for test10.f90 (code 1)
